Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing biogas, in particular to a device for manufacturing biogas from Chaohu blue algae. Background Art

[0002] The harmless treatment and resource utilization of algae mud and agricultural planting and breeding wastes are important tasks in the comprehensive management of Chaohu Lake pollution and basin ecology. The anaerobic digestion energy disposal solution has more significant comprehensive benefits such as complete harmless treatment of wastes, clean energy and efficient organic fertilizer output. It is a better direction for the deep treatment and comprehensive utilization of organic wastes such as algae mud, straw, livestock and poultry manure.

[0003] When using algae mud to produce biogas, a CSTR anaerobic reactor is required for fermentation. In order to improve the fermentation efficiency, it is necessary to ensure that the reaction temperature of the CSTR anaerobic reaction is in a constant state. However, when the existing CSTR anaerobic reactor is in use, colder raw materials enter the CSTR anaerobic reactor during the loading and unloading process, causing the temperature of the CSTR anaerobic reactor to drop sharply. It takes a while to heat up the temperature. At the same time, the sealing effect at the loading and unloading ends is not good, and the biogas slurry is easy to flow back from the loading and unloading ends, resulting in energy escape from the CSTR anaerobic reactor. Therefore, a Chaohu blue algae biogas production equipment is proposed. Utility Model Content

The controller is connected to motor 1, motor 2, a water pump, a push rod motor, a power interface, a data interface, a switch and a display, and the controller adopts an ARM single-chip microcomputer.

[0057] Working principle:

[0058] In the process of producing biogas from blue algae, the salvaged algae mud and the ingredients straw and feces are put into the buffer box 2 for pre-storage and loading, and then the raw materials are rotated and transported to the fermentation component 1 for fermentation through the loading component 3. In the loading process, the temperature regulating component preheats the raw materials in the loading process to increase the temperature of the input raw materials. During the fermentation process, the unloading component 4 is used to discharge the fermented biogas slurry from the fermentation component 1. At the same time, the bottom of the loading component 3 and the unloading component 4 are blocked by a sealing mechanism during the unloading and unloading processes to prevent the biogas slurry in the fermentation component 1 from flowing back from the loading component 3 and the unloading component 4 when the pressure is too high.

[0059] When loading, the push rod motor is started, so that the cross bar drives the push-pull rod 34 to move downward along the length direction of the rotating tube 32. When the push-pull rod 34 moves downward, the docking hole 8 213 located on the push-pull rod 34 moves to the docking groove 211 of the inner circle of the rotating tube 32 and communicates with the docking groove 211. At the same time, when the push-pull rod 34 moves downward, it drives the closing mechanism to move downward, and the sealing plate 53 on the closing mechanism does not conflict with the bottom of the rotating tube 32 downward, so that the sealing plate 53 does not seal the bottom of the rotating tube 32, so that the raw material enters the fermentation box 11 along the bottom of the sleeve 31, and the biogas slurry in the fermentation box 11 can be discharged from the fermentation box 11 from the bottom of the sleeve 31;

[0060] When the movable plate 51 moves downward with the sealing plate 53, the movable plate 51 drives the adjustment plate 21 to slide downward, and the connection hole 1 22 on the adjustment plate 21 moves downward to the position of the connection hole 24 on the sleeve 31. At this time, the connection hole 1 22 and the connection hole 24 are connected, and the adjustment plate 21 does not block the connection hole 24, so that the heating medium in the heating chamber can enter the inside of the connecting channel 1 25 along the connection hole 1 22 and the connection hole 24, and then enter the connection hole 4 28 on the conveying blade 37 along the connection hole 3 27 at the bottom of the driven ring 26, and then enter the guide cavity 29 inside the conveying blade 37 along the connection hole 4 28, so that the heating medium heats the conveying blade 37, and preheats the raw material when the conveying blade 37 performs bolt conveying on the raw material. At the same time, the medium enters the docking groove 212 along the guide cavity 29 and the connection hole 6 211, and then enters the water pipe 1 215 along the docking hole 8 213 and the drainage channel 214 and flows back to the heating box;

[0061] During the feeding process, the closing mechanism is removed from the bottom of the sleeve 31 of the feeding mechanism 4 in the same manner as described above, and then the biogas slurry is transported out of the fermentation box 11 by means of a spiral transporting method using the transport blades 37. During the fermentation process, the biogas slurry is stirred and mixed by the stirring shaft, and the heat conducting plate 12 is heated by the heating medium transported from the heating box to ensure that the temperature inside the fermentation box 11 is maintained within a certain range and the fermentation environment is stable.

[0062] The design first uses a blocking method to block the loading and unloading ends. When loading and unloading are not in progress, the loading and unloading ends are ensured to be in a blocked state to prevent the sludge inside the fermentation tank from flowing back from the loading and unloading ends under high pressure, and to prevent the sludge from flowing back and causing energy to escape from the fermentation tank, thereby reducing energy loss, ensuring the internal temperature of the fermentation tank is stable, and improving fermentation efficiency. During the loading process, the raw materials are preheated at the same time, and the raw materials entering the fermentation tank are heated to prevent the raw materials from being too low in temperature when entering the fermentation tank, thereby reducing the heating time of the fermentation tank and improving fermentation efficiency.

[0063] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
